[Will] didn’t pick up a card, rose, and bottle of wine for Valentine’s Day like most guys. Nope, he planned way ahead and built this color-selectable glowing Valentine. When we first saw it, we figured he threw some LEDs together with a microcontroller and edge-lit a piece of acrylic. While that is technically what happened, there was a lot more design and craftsmanship at play here than you might think.

First off, the controller board is a beautifully designed two-sided PCB which he etched rather than throwing a mess of wires and hot glue into an enclosure. Speaking of enclosures, he grabbed a wooden picture box from the big box store and used a piece of brass plate stock to serve as the control panel. The enclosure was finished with tinted polyurethane after having a slit added to the top for the acrylic. The message itself was milled using an engraving bit and a Dremel tool. This was done by hand and we think achieves a finished look that is comparable to the CNC milled ornaments we’ve seen in the past.
